002050fa97 feat(frontends/lean): increase binding power of ! and @
Remark: I did not add the constant "app".
Reason: It would break the standard library in many places.
Moreover, the current "max" is not just the binding power of
application, but also the binding power of identifiers, (, [, ...
It would be weird to call it "app"

e48df78938 feat(frontends/lean/elaborator): do not apply delayed_coercions on equation lhs
The variables in the equation lhs do not have type at preprocessing
time (i.e., their type is a metavariable). So, they may seem candidates
for delayed_coercions. If the coercions are injected, we will not be
able to pattern match. Thus, we disable coercions in this case.

8723f5b613 fix(frontends/lean/inductive_cmd): inductive datatype elaborator was 'fixing' parameter mismatches.
Given a datatype C with parameters As, if the declaration contained
(C Bs), the elaborator would silently replace it with (C As).

This bug would confuse users and make them believe they define something
different.
